There is gap of 4 between numbers
8+4 = 12
3+4 = 7
9-5 = 4
simillarly
?-4 = 6=> ?=10

Logic: For every row First column*2 + Second Column*3 = Third Column
for second row 9*2 + 17*3 = 69
for third row 13*2 + 11*3 = 59
for first row, lets say first column value is x, thus
x*2 + 13*3 = 49
2x = 49 – 39 = 10
x = 5
14, 10, 8
9, 16, 7
10, ?, 9
How?
Actually the sum of the first two rows is 32
so the missing number should be 32-10-9=13.
Find the missing section
IF 11 = 20
12 = 31
13 = 42
14 = 53
Then 18 = ?
Answer is 97.
How?
11 => (1+1)(1-1) => 20
12 => (2+1)(2-1) => 31
13 => (3+1)(3-1) => 42
14 => (4+1)(4-1) => 53
similarly
18 => (8+1)(8-1) => 97
